of the character. This allows to access all files, even those not

- PATH_MAX is now 4096. Internally, path names can be as long as the
underlying OS can handle (32K).
- struct dirent now supports d_type, filled out with DT_REG or DT_DIR.
All other file types return as DT_UNKNOWN for performance reasons.
- The CYGWIN environment variable options "ntsec" and "smbntsec" have
been replaced by the per-mount option "acl"/"noacl".
- The CYGWIN environment variable option "ntea" has been removed without
substitute.
- The CYGWIN environment variable option "check_case" has been removed
in favor of real case-sensitivity on file systems supporting it.
- Creating filenames with special DOS characters '"', '*', ':', '&lt;',
'&gt;', '|' is supported.
- Creating files with special DOS device filename components ("aux",
"nul", "prn") is supported.
- File names are case sensitive if the OS and the underlying file system
supports it. Works on NTFS and NFS. Does not work on FAT and Samba
shares. Requires to change a registry key (see the user's guide).
Can be switched off on a per-mount base.
- Due to the above changes, managed mounts have been removed.
- Incoming DOS paths are always handled case-insensitive and get no POSIX
permission, as if they are mounted with noacl,posix=0 mount flags.
- unlink(2) and rmdir(2) try very hard to remove files/directories even
if they are currently accessed or locked. This is done by utilizing
the hidden recycle bin directories and marking the files for deletion.
- rename(2) rewritten to be more POSIX conformant.
- access(2) now performs checks using the real user ID, as required by
POSIX; the old behavior of querying based on effective user ID is
available through the new faccessat(2) and euidaccess(2) APIs.
- Add st_birthtim member to struct stat.
- File locking is now advisory, not mandatory anymore. The fcntl(2) and
the new lockf(2) APIs create and maintain locks with POSIX semantics,
the flock(2) API creates and maintains locks with BSD semantics.
POSIX and BSD locks are independent of each other.
- Implement atomic O_APPEND mode.
- New open(2) flags O_DIRECTORY, O_EXEC and O_SEARCH.
- Make the "plain file with SYSTEM attribute set" style symlink
default again when creating symlinks. Only create Windows shortcut
style symlinks if CYGWIN=winsymlinks is set in the environment.
- Symlinks now use UTF-16 encoding for the target filename for
better internationalization support. Cygwin 1.7 can read all old style
symlinks, but the new style is not compatible with older Cygwin releases.
- Handle NTFS native symlinks available since Vista/2008 as symlinks
(but don't create Vista/2008 symlinks due to unfortunate OS restrictions).
- Recognize NFS shares and handle them using native mechanisms.
Recognize and create real symlinks on NFS shares. Get correct
stat(2) information and set real mode bits on open(2), mkdir(2)
and chmod(2).
- Recognize Netapp DataOnTap drives and fix inode number handling.
- Recognize Samba version beginning with Samba 3.0.28a using the new
extended version information negotiated with the Samba developers.
- Stop faking hardlinks by copying the file on filesystems which don't
support hardlinks natively (FAT, FAT32, etc.). Just return an error
instead, just like Linux.
- List servers of all accessible domains and workgroups in // instead of
just the servers in the own domain/workgroup.
- Support Linux-like extended attributes ([fl]getxattr, [fl]listxattr,
[fl]setxattr, [fl]removexattr).
- New file conversion API for conversion from Win32 to POSIX path and
vice versa (cygwin_conv_path, cygwin_create_path, cygwin_conv_path_list).
- New openat family of functions: openat, faccessat, fchmodat, fchownat,
fstatat, futimesat, linkat, mkdirat, mkfifoat, mknodat, readlinkat, renameat,
symlinkat, unlinkat.
- Other new APIs: posix_fadvise, posix_fallocate, funopen, fopencookie,
open_memstream, open_wmemstream, fmemopen, fdopendir, fpurge,
mkstemps, eaccess, euidaccess, canonicalize_file_name, fexecve, execvpe.

- Getting a domain user's groups is hopefully more bulletproof now.
<itemizedlist mark="bullet">
- Cygwin now comes with a real LSA authentication package. This must
be manually installed by a privileged user using the /bin/cyglsa-config
script. The advantages and disadvantages are noted in
http://cygwin.com/ml/cygwin-developers/2006-11/msg00000.html

- Cygwin now allows storage and use of user passwords in a hidden area of
the registry. This is tried first when Cygwin is called by privileged
processes to switch the user context. This allows, for instance,
ssh public key sessions with full network credentials to access shares
on other machines.

ease use in multi-machine and multi-domain environments. The existing
options have a slightly changed behaviour.

- Fallout from the long path names: If the current working directory is
longer than 260 bytes, or if the current working directory is a virtual
path (like /proc, /cygdrive, //server), don't call native Win32 programs
since they don't understand these paths.

- On the first usage of a DOS path (C:\foo, \\foo\bar), the Cygwin DLL
emits a scary warning that DOS paths shouldn't be used. This warning
may be disabled via the new CYGWIN=nodosfilewarning setting.

Cygwin automatically uses cygserver if it's available.

- Don't force uppercase environment when started from a non-Cygwin process.
Except for certain Windows and POSIX variables which are always uppercased,
preserve environment case. Switch back to old behaviour with the new
CYGWIN=upcaseenv setting.

- Different Cygwin installations in different paths can be run in parallel
without knowing of each other. The path of the Cygwin DLL used in a
process is a key used when creating IPC objects. So different Cygwin
DLLs are running in different namespaces.

- Each Cygwin DLL stores its path and installation key in the registry.
This allows troubleshooting of problems which could be a result of having
multiple concurrent Cygwin installations.
